The closest I come to that is do some crude drawings of parts I replace or take out for cleaning. I don't start to question things until I start the rebuild process. I'm not sure I could even reproduce a schematic from looking at the wiring in the radio, I'd probably miss some wires or connections. I do admire people who can and do this. I have found times when Philco uses resistors that are not available any more so I just use the closest value and then measure to get closer to what was there.
